Answer: 364 with a remainder of 28
Step-by-step explanation:
14952/41
41 goes into 149 3 times
149 - (41 *3)
149 - 123 = 26
41 goes into 265 6 times
265 - (41*6)
265 - 246 = 19
41 goes into 192 4 times
192 - (41*4)
192 - 164 = 28
So 14952/41 = 364 with a remainder of 28
There are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies.
4/25 prefered digital copies
21/25 prefered hard copies
21 is more than 4.
The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the correct answer.
